Well-known Australian Second World War poster promoting the importance of keeping quiet. The poster depicts a sulfur-crested cockatoo, known for their noisiness behind the text 'those who talk don't know'; and to contrast, an owl, often regarded as quiet and wise, in the bottom left corner next to the text 'those who know don't talk!' The poster implies that it is smart and wise to stay quiet if the audience has information, and that those who preach what they think they know are generally misinformed.
